FREDERICK GARREGHT, OF IDAHO CITY, IDAHO.

EXTENSIBLE ELECTRIC-LIGHT FIXTURE.

Specification of Letters Patent.

Application filed May 14, 1913.

Patented May 5, 1914:.

Serial No. 767,525.

To all whom it may concern Be it known that I, Fnnnnnion GAnRnoHT, a citizen of the United States, and a resident of Idaho City, in the county of Boise and State of Idaho, have invented a new and Improved Extensible Electric-Light Fixture, of which the following is a full, clear, and exact description.

My invention relates to suspended electric light fixtures employing a flexible suspending means having a spring acted winding drum or barrel, and a lazy-tongs composed of hollow members to receive the conductor wires.

It is a design of my invention to provide a novel means for mounting and securing the winding drum, its frame and spring.

It is a further design of the invention to provide novel guiding means for the flexible extension elements.

The invention also has for its design the provision of means for preventing the lazytongs from swaying.

It is also a design of my invention to improve in various particulars devices of the general character indicated, to the end that efficiency in operation may be promoted, as well as economy of manufacture and simplicity of adjustment and control.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is an elevation of an extensible electric light fixture embodying my invention; parts being broken away; Fig. 2 is a similar view taken at right angles to Fig. 1, the arms of the chandelier being in section; Fig. 3 is an enlarged sectional plan view, parts being omitted; Fig. 4. is a vertical section approximately on the line H of Fig. 3; Fig. 5 is a detail sectional view of the drum nipple and spring; and Fig. 6 represents a cross section of one of the arms of the lazytong's.

In constructing a fixture embodying my invention in accordance with the illustrated example, arms 10 carry, in practice, any clesired form or design of chandelier, the arms extending from the opposite side of any suitable fitting 11. Suspension chains or other flexible elements 12 are secured at their lower ends in any suitable manner, as by collars 12 to the arms 10, the upper ends of the chains passing over idler pulleys 13 on the frame 14 of a spring-acted winding barrel or drum 15. The said frame and barrel are secured in place by a nipple 16passing axially therethrough, the nipple being adapted at its upper end to be connected with a ceiling pipe 17 the said nipple in practice being threaded exteriorly and interiorly to receive ceiling pipes of different diameters. At the lower end of the nipple 16 a pipe section 18 is connected, which in turn has connection with the upper end of a lazytongs 19, the lower end of which has connection =with the fitting 11 of the chandelier arms 10. A shell 20 is employed as a cover for the frame 1 1 and the spring barrel.

The nipple 16 is slotted from the lower end upwardly, as at 16 and the spring 21 has its inner end 21 turned inwardly, as shown in Fig. 5, and in assembling the parts the spring 21 is placed in the drum through the open top thereof that has any suitable closure 15 and the spring and drum are passed laterally between the upper and lower members of the frame 14. The nipple is then passed downwardly through the frame and drum, the inturned end of the spring entering the slot 16*. A key 14* is passed transversely in a slot 14 in the upper frame member and through a transverse orifice in the nipple 16, thereby sustaining the frame and spring in position. Above the frame a lock nut 22, has threaded engagement with the exteriorly threaded end of the nipple to prevent vertical movement of the frame. The connection between the pipe-section 18 and the lower end of the nipple 16 may be efiected by a union 23, the upper end of which may have threaded engagement either with the interior or exterior of the nipple, as may be desired.

The conductor wires in practice pass downwardly as usual through the ceiling pipe 17 and with my improved construction are passed through the nipple 16 and through the arms of the lazytongs, said arms being hollow and having a sliding cover 19*. In order to prevent the lazytongs from swaying .on the pivotal connection at 19 with the pipe section 18, I provide additional arms 19" at the upper end and connect the same pivotally with a sliding collar 25 on said pipe section. The collar, it will be obvious, thus prevents the swaying of the lazytongs, since said collar will have guided movement up and down on the pipe section.

In order to prevent the chandelier from i being tilted laterally on its pivotal connection 19 of the lazytongs, should the chains be drawn too taut, I provide a guide 26 having lateral arms 26, which are perfo rated for the passage of the chains 12, the said guide being held between the fitting 11 and the member 27 to which the lower ends of the lazytongs are pivoted.

The provision of the novel nipple 16 and the manner of securing the same to the frame 14:, spring barrel 15 and spring 21., provide a very simple construction, enabling the parts to be quickly and properly assembled and secured. The nipple also forms a convenient and efiicient means for connecting the pipe section 18 or equivalent suspending member and for connecting the fixture with the ceiling pipe. The sliding sleeve may in practice, be of such a weight as to constitute a counterbalance.

The drawings show the upper end of the sleeve enlarged and thickened as at 25, to give the necessary weight to partially or fully constitute a counterbalance.

Having thus described my invention, I claim as new, and desire to secure by Letters Patent:

1. An extensible electric light fixture, comprising a drum, flexible elements winding on said drum and adapted to suspend a chandelier, a lazytongs to carry conductor wires, means for connecting the lazytongs with a chandelier, a nipple adapted for connection with a ceiling pipe and having connection with the upper end of the lazytongs, said nipple extending axially through the drum, a coil spring within the drum, a frame for said drum, the nipple having a slot extending from one end thereof and the spring having an inturned end entering said slot, and means for detachably securing the frame to the nipple.

2, In an extensible electric light fixture, flexible means to suspend achandelier, a nipple adapted to connect with a ceiling pipe, a frame, a drum in said frame, a coiled spring in said drum, said nipple passing through the frame, the drum and spring, and

secured to the frame, a lazytongs adapted to carry a light fixture; means for connecting the lower end of the nipple with the upper end of the lazytongs, the spring having detachable slidable engagement with the nipple, and the frame having rollers over which the flexible elements run.

3. In an extensible electric light fixture, flexible means for suspending a chandelier,

' means for winding the flexible means, a lazy tongs for receiving conductor wires, means for connecting th fixture with an overhead support, said means including a tubular member having pivotal connection with the lazytongs, a sliding member having guided movement on said tubular member, and arms pivotally connected with the lazytongs and with the said sliding member.

l. In a lighting fixture, securing means adapted to be connected with a support, a fitting adapted to carry the illuminating de vices, extensible means to raise and lower the fitting relatively to the securing means, said extensible means including a lazytongs connected near one end with the securing means and at the other end with said fitting, and a device to prevent swaying of the lazytongs, said device consisting of a member having sliding guided movement longitudinally of the securing means and pivotally connected with the lazytongs.

5. The combination of lazytongs, securing means for one end of the lazytongs having pivotal connection with the latter, a fitting pivotally connected with the opposite end of the lazytongs and movable toward or from the securing means in response to the con traction or extension of the lazytongs, and a slide having guided movement on the securing means and pivotally connected with the adjacent end of the lazytongs.

G. lhe combination of lazytongs, securing means for one end of the lazytongs having pivotal connection with the latter, a fitting pivotally connected with the opposite end of the lazytongs and movable toward or from the securing means in response to the contraction or extension of the lazytongs, and a slide having guided movement on the securing means and pivotally connected with the adjacent end of the lazytongs, the said slide being weighted to constitute a counterbalance.
